1762. Buildings With an Ocean View
Stack, Array, Monotonic Stack, AMateList ·Problem Statement
link: LeetCode.cn LeetCode There are n buildings in a line. You are given an integer array heights of size n that represents the heights of the buildings in the line.
The ocean is to the right of the buildings. A building has an ocean view if the building can see the ocean without obstructions. Formally, a building has an ocean view if all the buildings to its right have a smaller height.
Return a list of indices (0-indexed) of buildings that have an ocean view, sorted in increasing order.
Example:
Input: heights = [4,2,3,1]
Output: [0,2,3]
Input: heights = [4,3,2,1]
Output: [0,1,2,3]
Input: heights = [1,3,2,4]
Output: [3]
Constraints: 1 <= heights.length <= 105 1 <= heights[i] <= 109
